        signal_name: String,
        timeout_ms: Option<u64>,
        next: Option<Box<SerializableContinuation>>,
    },
}

A serializable workflow continuation (stores only IDs and structure).

This type can be serialized/deserialized and later converted back into a runnable WorkflowContinuation using a TaskRegistry.

Serialization

// Serialize a workflow
let serializable = workflow.continuation().to_serializable();
let json = serde_json::to_string(&serializable)?;

// Deserialize and convert to runnable
let serializable: SerializableContinuation = serde_json::from_str(&json)?;
let continuation = serializable.to_runnable(&registry)?;

Implementations

impl SerializableContinuation

pub fn to_runnable( &self, registry: &TaskRegistry, ) -> Result<WorkflowContinuation, WorkflowError>

Convert this serializable continuation into a runnable WorkflowContinuation.

Looks up each task ID in the registry to get the actual implementation.

Errors

Returns WorkflowError::TaskNotFound if any task ID is not in the registry.

pub fn task_ids(&self) -> Vec<&str>

Get all task IDs referenced in this continuation.

pub fn compute_definition_hash(&self) -> String

Compute a SHA256 hash of this continuation’s structure.

This hash serves as a “version” identifier for the workflow definition. It can be used to detect when a serialized workflow state was created with a different workflow definition than the current one.

The hash is computed from the canonical structure of task IDs and their arrangement.

Trait Implementations

impl Clone for SerializableContinuation

fn clone(&self) -> SerializableContinuation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SerializableContinuation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SerializableContinuation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for SerializableContinuation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
